The answer to the question you are looking for is right in front of u
So basically the answer would be A and C bestie♂️
A the slope of the line is 1
to calculate the slope m , use the ' gradient formula '
m = ( y₂ - y₁ ) /( x₂ - x₁ )
where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)
m =
=
= 1
So assuming 1 3/4 feet by feet means 1 3/4 feet by 1 foot,
island actual dimentions=1 3/4 feet by 1 foot
scale=1 inch=1 feet
logically, blueprints are smaller so for every real foot, 1 inch is drawn on the scale
so change every foot to inch
so the island on the blueprint=1 3/4 inch by 1 inch
